| Abstract: | The stability constant of the coordination compounds of Cu(Ⅱ) with imidazole, benzimidazole, 2-methylbenzimidazole, 2-ethylbenzimidazole and 2-propylbenzimidazole were calculated through the measurement of pH values of the solution where the reaction took place using pH titration at 25℃, in the presence of 0.1mol/L KCl. The protonation of these imidazole compounds were calculated using the same method. |

| Keywords: | pH titration method imidazole benzimidazole stability constant |
